Application filed July 5, 1906. Serial No. 324,810.

New York, county of New York, State of New York, have invented certain new and useful Improvements in X-Ray Apparatus, of which the following is a specification.

' This invention relates to K-ray apparatus ratus whereby the "rays can bemore easily directed to a specificobject and whereby surrounding objects and the operatorcan be perspective view of an apparatus. embody-- ing m invention; Fig. 2 is a-sirnilar view with t e parts in slightly different positions; and Fig. 3 shows'an-- elevation and crosssection of one of a series of shields used with the apparatus.

1 in'd'cates a of base bars 2, uprights 3, and top bars 4, all

of which may. be suitablybraced as by rods 5. The width of the frame'is such that an operating table may beplacedbetween the uprights 3, and, the frame is mounted upon casters 6 for convenience in moving it about. The uprights 3 are preferably formedof angle iron for the purpose/ of giving strength to the structure and also'to form guide-ways for the vertically fsliding members 7 an ranged between them 'as shown in the drawings. Pivotallyfmounted on and arranged between the sliding members is the housing 8 for the -X-ray tube. The tube itself is not shown, but it will be understood that it is adapted to be arranged within this housing 8 and suitably connectedwith-the source of electricity. The housing 8 is box-shaped and is lined with lead or other ray-proof substance and is provided in one of "its sides with an aperture 9' which may be more or and may be attached to the boX by means of bayonet joints 12 fitting over suitable projections 13 arranged adjacent the aperture 9. The purpose of more or less contracting the aperture is to allowof the direction of the rays to a more or less contractedarea as may be desired by. the operator. The top of the box is closed by ailead lined cover'let hinged thereto, and arranged at a-convenient place in the cover or in some other part. of the housing is a window 15. formed of lead glass, for the purpose of observation. Each of the sliding members 7 is connected to a weight .16 by cords l7ypassing over suitable pulleys 18 at the'top of theframe. The weight 16 corresponds approximately to the weight of the sliding members, the housing and the fluoroscope (hereinafter mentioned), and is preferably guided in a tube 19 mounted in the frame.

21 passing over a pulley 22 on an arm 23 projecting from one of the top bars 4 of the frame, said cord further. extending over other pulleys 2a and having, connection with the Weight 16. This cord 2lis of proper length to hold the fluoroscope in1line with the aperture 9 in the housing. The essential feature .7 v of'this part of the invention is that the frame constructed preferably fluorosoope is counter-weighted and its cord may be connected with the weight 16 or it may be provided with a separate weight, whereby the housing and the fluoroscope may be moved independently of each other.

It will be seen from the drawings andthe abovedescription, that'the housing 8- containing the X-raytube may be easily raised or lowered and will remain at any desired elevation by reason of its perfect counterbalance also that the fluoroscope when at .tached to the same counter weight'will follow the vertical movements of the housing and always remain in operative position 0 posite the aperture 9. Further it will e seen that by the constructionand arrangement above set forth the. housing 8 may be tilted to any desired angle and the rays is- The fluoroscope 20 is suspended bya cord i self being meanwhile fully protected from any injurious effects which might be caused by the rays, andthe clearness of 'an X-ray photographic plate being insured by thus eliminatingotherwise interfering secondary rays.

details of ,construction and arrangement of parts, may be made without departing from It is obvious that many changes in the I the 'spirit of the invention, and the forms indicated in the drawings are merely typical to explain the nature of the invention.

Having described my invention what I claim is, p

1. In an X-ray apparatus, a'supporting frame comprising palrsof spaced side members, a slide in sliding engagement with each pair of spaced side members, an X-ray tube housing mounted on horizontal pivots in the slides, a tube connected with the supporting frame, and a. counterbalance weight in the tube connected to the slides.-

"shield -.tube, the .flan e being provided with open circumferentia slots, and ing engaging the slots.

In testimony whereof in presence of two witnesses.
